I don't really understand other people,
 but I don't know myself that well, either.
Ich kann andere Menschen
nicht verstehen,
No comprendo a los demás y tampoco
me conozco bien a mí mismo.
No entiendo muy bien a los demás,
pero tampoco me entiendo a mí mismo.
J’ai du mal à comprendre les gens,
y compris moi-même.
A dire il vero, 
non è che sappia capire gli altri,
Eu nem entendo as outras pessoas,
mas também não me conheço muito bem.
Я с трудом понимаю не только других…
